FAQ
How many production lines in your factory?
5 production lines
How long is your delivery time?
One week for spot goods, 60 days for orders
Can you design the equipment according to our size?
Yes
What does the overhaul kit include?
It typically contains seals, O-rings, valves, spacers, springs, and other wear components specific to your injector or HP pump model.
Can these kits be used by non-professionals?
While technically possible, professional tools and knowledge are recommended to ensure correct disassembly, reassembly, and calibration.
Are these kits universal?
No. They are model-specific. You must select the correct kit based on the injector or pump model (e.g., Bosch CP3, Delphi injectors, etc.).
Will using a repair kit affect engine calibration?
Repaired injectors or pumps may require re-coding or recalibration through diagnostic tools for best performance and emissions compliance.
How often should injectors or pumps be overhauled?
Typically every 100,000–150,000 km, or when symptoms like rough idle, poor fuel economy, hard starting, or injector leaks appear.
